Operational appropriateness of a function-oriented interface design approach, the Ecological Interface Design was investigated in a collaborative experimental study among HRP, UofT and VTT. In the study the EID concept was compared with two more traditional interface designs in six scenarios representing two levels of uncertainty about the situation and required action (within and out of design). Six NPP crews participated in the tests. This paper summarises the results achieved by VTT who was responsible for a detailed qualitative analysis of operator performance. The tentative results indicate that a direct relationship between the interface type and the performance outcome is visible in the “within” design scenario but not in the “out” scenario. There is, however, indication of a more generic but complex connection. Hence, an interpretation of situational demands, availability of interface affordances, and prehensility to make use of the affordances is needed to achieve a good outcome. The result should be tested on the available further data. Thereafter, the qualitative analyses will be put in a dialogue with the results achieved in the statistical analysis of the data.
